1. Percy encounters many mythical creatures on his quest. Examples include Hippocampi, Harpies, Hyrdra, and Charybdis. Using the descriptions in the text, draw one of these creatures on a blank piece of paper. If there is another creature from the book you prefer to draw, you can do that, too.Hippocampi are described on page 109; Harpies on page 110; Hydra on page 143; and Charybdis on page 160.

2. Draw a map of the East Coast of the United States. Be sure to include real places like New York City and Miami and mythical ones like Camp Half-Blood and the Sea of Monsters. Then, label your map with a legend using symbols to represent the important event that occurred at each location. For example, for the Cyclops Island, you may want to draw a golden fleece.

3. Look at the list of names below. On the blank line next to each half-blood, write the name of his or her immortal parent. See how many you can remember before looking in the book.
